What Is Brewer’s Yeast?
Brewer’s yeast is a fungus made from the one-celled Saccharomyces cerevisiae. It is predominantly used in the brewing of alcoholic beverages, and hence its name. Brewer’s yeast is also used in making bread, although it is different from baker’s yeast. Brewer’s yeast is quite popularly used as a nutritional supplement since 52% of it is protein, and is also an excellent source of B-complex vitamins (1).

Is It Safe To Take Brewer’s Yeast While Breastfeeding?
It is not known if brewer’s yeast is safe when you are breastfeeding since there is insufficient scientific research on it. Medical experts suggest the mothers consult a doctor before having it.
Does Brewer’s Yeast Help Improve Breast Milk Supply?
Probably. Brewer’s yeast has been traditionally used as breast milk stimulant. Despite its long-standing use as a galactagogue, there is little scientific evidence to suggest that it works. A study found brewer’s yeast efficacy ambiguous, as it was with other galactagogues (2).
While the fungus’ milk-stimulant properties have been anecdotal, lactating mothers can use brewer’s yeast as milk stimulant after doctor consultation. Do keep in mind that the effects of this yeast may vary from person to person.
What Is The Ideal Dosage Of Brewer’s Yeast During Lactation?
Health experts state that three tablespoons of brewer’s yeast a day are ideal during lactation (3). If you do not see any improvement in your breast milk production, then you can increase the quantity by half-a-teaspoon a day. If you do not see any improvement in your breast milk even after several weeks of consumption, then it is best to stop and consult a doctor.
How To Take Brewer’s Yeast When Breastfeeding?
Brewer’s yeast is available in the form of tablets and powder. You can add the recommended quantities of the powder by adding it to preparations like cookies or have it dissolved in water. There is no fixed dosage for brewer’s yeast tablets since the content of the yeast in a tablet varies, depending on the manufacturer. So the dosage can go as high as eight tablets a day.
It is best to stick to the powdered version to ensure you get the correct dosage.

What Are The Health Benefits Of Brewer’s Yeast?
Brewer’s yeast is an excellent source of vitamins and micronutrients, which eventually prevent deficiency diseases. It is also a good source of protein for those who need it in large quantities. Brewer’s yeast is known to improve some conditions like acne (1).
Individuals with diabetes may show better glucose tolerance when provided with a controlled amount of brewer’s yeast daily.
Below are the vital nutrients found in brewer’s yeast (4):
- Protein in the form of 16 types of amino acids
- All B-complex vitamins
Brewer’s yeast is often considered a nutritional supplement for vitamin B-complex and the micronutrient selenium.
Are There Any Side Effects Of Brewer’s Yeast?
Yes. Some individuals could display an allergic reaction to brewer’s yeast. Symptoms of an allergic reaction include nausea, vomiting, skin hives with intense itching, and abdominal pain. You may also experience side effects such as a headache, bloating of the stomach, and gassiness. Severe allergic reactions can cause anaphylactic shock, where the immune system floods the body with chemicals, causing a shock, an increase in blood pressure and narrowing air passages (breathing becomes difficult).
Since brewer’s yeast has the potential to cause side effects, you should avoid it in some situations.
When To Avoid Brewer’s Yeast?
You must avoid having brewer’s yeast in the case of:
- History of food allergies: If you develop an allergy to any new food, then you must avoid having brewer’s yeast. Those with allergies towards mushrooms, a type of fungus, should preferably avoid brewer’s yeast since yeast is a fungus too.
- Diabetes: Brewer’s yeast can lead to a sudden drop in blood sugar among diabetics who are on medication. Therefore, do not consume brewer’s yeast without doctor’s consultation if you have diabetes. However, when consumed in correct dosages as prescribed by the doctor, the yeast can be beneficial for pregnant women with diabetes.
- Having medicines for depression: Do not mix antidepressants with brewer’s yeast, which contains a compound called tyramine. Tyramine can react with monoamine oxidase inhibitors (MAOIs) and increase the blood pressure, thus putting the person at the risk of a heart attack or stroke.
- Inflammatory bowel disease (IBD): Those with an inflammatory bowel disease (IBD), especially Crohn’s disease, should not have yeast as it causes excessive flatulence and may lead to severe abdominal pain and discomfort.
- Do not mix with other galactagogues: If you are taking other galactagogues, then stop their consumption before having brewer’s yeast. Having multiple galactagogues together may cause a reaction and complicate things.
- Avoid in some cases: If you are prone to excessive flatulence, then you must consult a doctor before having brewer’s yeast. Those with a history of migraine should avoid yeast since a headache is one of its side effects. People with gout should also avoid this yeast since it can cause protein overload. Individuals on antifungal medication and a high protein diet should consult a physician before having brewer’s yeast.
The benefit of brewer’s yeast as a galactagogue could be inconclusive, but it still works great as a nutritional supplement. Since decades, mothers have been using the yeast for breast milk supply, and there is no harm giving it a try. But consult a doctor before trying brewer’s yeast. If it works for you, then you can make it a part of your daily healthy diet.
